in Search ofPerfect Li hL But obstacles were still to be overcome. For example, the tungsten paste filament was fragile. The first MAZDA lamp gave more light and cheaper light, yet left something still to be added-greater sturdiness fully to meet the strain of everyday usage. Then the triumph of the drawn wire fila ment in the MAZDA lamp of today-three times as much light as the old style carbon lamps, with the same amount of electric cur rent, and rugged enough in elements and construction to round out the full wonder of its practical efficiency. The plodding scientists had climbed a step higher in the great world-journey between the humble candle and the ideal light. Will they stop here? Will that group of scien tists in the Research Labor atories of the General Elec tric Company at Schenec tady be satisfied with these selected methods of con- struction revealed by the lamp marked MAZDA? The mark MAZDA itself answers that question. MAZDA is the mark of a Service and it designates the great plan by which the MAZDA lamp shall con tinue to mean the highest achievement in incandescent lighting. MAZDA The MAZDA Lamp Se rvice of today which gives three times as much means that light as carbon the Rese h lamps. It embodies the he Research results of MAZDA ILaboratories Service to the manu facturers. are not only assembling the results of their own incessant and exhaustive investigations, and those of their associates in the active developing and manufacturing centers at Cleveland and Har rison, but are keeping in close touch with great experimental lamp laboratories in Europe, MAZDA Service means also the furnishing to the General Electric Company factories, Even the shape of and to the factories of other glass bulbs is a subjectforconstant Companies entitled to receive experimentation, this Service, every new frag ment of knowledge, from whatever source derived, which shall be selected in the course of this service to the manufacturers for em bodiment in the MAZDA lamp. In other words, the mark MAZDA on a lamp means that this world-wide MAZDA Service has been received by the makers of that lamp.
